LAN9668/9MX

Controllers Overview

The LAN9668/9MX is an eight-port Time-Sensitive Networking (TSN) Ethernet switch integrated with an Arm Cortex-A7 processor. It supports 10/100/1000 Base-T PHYs and interfaces including RGMII, RMII, and SGMII. The device operates within a temperature range of -40°C to 85°C and utilizes a 256-HSBGA package measuring 14x14 mm. Power supply voltage is 1.1V, with a Moisture Sensitivity Level (MSL) of 3 (168 hours).

Controllers Feature Summary

• Integrates an Arm Cortex-A7 processor for application processing alongside switching functions.
• Supports IEEE TSN standards including 1588v2, 802.1AS-2020, 802.1Qci, 802.1Qav, 802.1Qbv, and 802.1CB.
• Provides eight ports with integrated 10/100/1000 Base-T PHY capabilities.

Controllers Applications

• Industrial automation networks requiring precise time synchronization.
• Edge computing devices utilizing the integrated Cortex-A7 core.
• Automotive infotainment and connectivity systems.

Controllers Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm commercial or industrial grade designation. Confirm package type and moisture sensitivity level requirements during handling. Ensure compatibility with supporting PHYs like the LAN8814 if external physical layer components are required for the design.

Controllers Selection Notes

Select this component for designs requiring integrated switching and processing in a compact footprint. Compare port counts and interface options with the LAN9662 variant if fewer ports suffice. Validate thermal performance within the specified operating temperature range for the target environment.

Controllers Part Context

This part belongs to the LAN9668 series of TSN switches from Microchip Technology. It is designed to work with supporting devices such as the LAN8814 PHYs to reduce system complexity. The series targets markets demanding deterministic latency and high clock precision.

Controllers Replacement Considerations

Publicly listed parameter-equivalent substitutes include the LAN9662-I/9MX, LAN9662/9MX, and LAN9668-I/9MX. Verify pinout and feature parity before substitution.
